Please note that day old chick sexing by professional chicken sexers is only 90% accurate. If you happen to win 'rooster lotto' we are unable to swap your male with a hen of this breed unfortunately as we simply do not have the stock available. If one of your chicks ends up being a male, you will be offered a refund of the original amount paid with your rooster removed for you free of charge OR you may take home an Isabrown hen or an Australorp hybrid hen at point of lay.
